Cost-efficient design of high pressure gas pipeline

The aim of this thesis was the cost-efficient design of high pressure gas pipeline with a maximum capacity 40 mil.Nm3/day and a length of the pipeline 100 km. The economic design consisted of analyzing and comparing expenses for three different pipelines over a 20-year period. The thesis includes the design of pipe dimensions with proposed thickness of pipe walls according to STN EN 1594: 2014 and ISO 4200: 2010. Software Simone was used in order to determine the pressure loss and the number of compressor stations. Software calculated the necessary power of compressor stations and fuel gas consumption as well. Based on the necessary power, the most economically advantageous gas turbine compressors were chosen for each compressor station. The capital expenditures consisted of the price for compressor stations together with gas pipelines. The operating expenditures for 20 years were added to these costs. In conclusion of the thesis, a comparison of expenditures for all 3 variants was conducted. Based on the results, it can be stated that the most economically advantageous variant of the construction is a gas pipeline with a diameter DN1000
